Blowing number 2 fuse in dash panel - 2000 GMC Jimmy

Whatever the fuse is connected to is Hooked up wrong and it is creating a short which blows the fuse! Good luck

DID YOU CHECK ANY FUSES? THERE ARE OFTEN 1 OR 2 FUSES CONTROLLLING THINGS LIKE THE DASH, INSTRUMENT PANEL, A/C...ETC. CHECK FUSES FIRST AND IF YOU ARE BLOWING FUSES CHECK THE FUSE PANEL IN WHICH THE FUSES ARE LOCATED. NEXT CHECK THE WIRES TO MAKE SURE YOU DONT HAVE WIRES GROUNDING. MICE CAN OFTEN BE THE CULPRIT TO CUT OR CHEWED WIRES. (MECHANIC FOR 2 YEARS AND ALWAYS HAVE WORKED ON MY OWN VEHICLES) ALSO THE STARTING COULD BE A COMPLETELY DIFFERENT PROBLEM. HOW MANY MILES DOES YOUR VEHICLE HAVE ON IT?

If you do not know where the fuse is, how do you know it needs "fixing"?
If your dash lights are not working, there is a possibility that there is a blown fuse. However, you need to realize that blown fuses do not cause electrical problems. Electrical problems cause blown fuses. So if you replace the fuse, it will likely just blow again if you do not fix the problem that caused it to blow.

On the other hand, there are several other things that could be keeping your dash lights from working that has absolutely nothing to do with the fuse.

With all that said, the fuse that protects your dash light circuits is a 7.5 Amp fuse that is located in the Instrument Panel Junction Block at the left side of the dash. It is marked "PANEL"

There's two an their both in the under dash fuse panel, sometimes the fuse does'nt blow and the ground wire just comes off the lighter socket. the one in the dash is on one fuse n all the rest Back doors and trunk are on the other fuse. It's the number 10 fuse and theirs only the one.in the left hand fuse panel under the dash to the left of the sr=eeringcolum it has a black plastic cover on it.

YOU HAVE TWO SEPERATE FANS TO BLOW THE AIR ONE IN FRONT AND ONE IN THE BACK CHECK THE FUSES FIRST UNDER THE DASH AND SECOND UNDER THE HOOD SHOULD BE ANOTHER ALSO CHECK THE RELAYS UNDER THE HOOD THE PUSE PANEL COVER SHOULD TELL YOU THE FUSE LOCATION AND NUMBER AND AMPERAGE OF THE FUSE

Check your tail light fuse, on the dodge ram the dash lights and tail lights use the same fuse so if the tail light fuse blows your dash lights will go out to alert you of no tail lights.

check for a problem neutral switch and wires
may find that switch is loose and grounding out the wire connections or plug

Check 2 fuses. Instument lights / panel and also the brake light fuse. Sometimes the brake light fuse blows and you have no dash lights.

i would check the grounding wires. have you tried going to higher ampage on the fuse? There is definitely a short somewhere

if you need to find the fuse panel, it's on the drivers side under the steering wheel there is a panel that looks like it's part of the dash itself...on each end of the dash piece you will see a knob... turn counter clockwise to release.. then the dash panel will fold down... after you fold it down you can remove it by popping it off the guides.... the fuse panel is behind the dash panel.... some models of car have an illustration of what fuse goes where... if you look close on the fuse panel next to each fuse there's a number.. each number will match the illustration on the dash panel insert...
